   Seems the idea here is to avoid "identification numbers".   
      
   Seems like a single person has multiple random identification numbers.   
      
   There random indentification numbers would need to be very big others there is   
   too much potential for conflicting and confusing random numbers.   
      
   Also the messages in which these are "broadcast" I presume would have to be   
   "anonymous". So no source ip and such.   
      
   There is one problem with it though.   
      
   Let's suppose random numbers X,Y,Z are from an infected person.   
      
   How does infected person re-broadcast these numbers to inform that this person   
   is infected.   
      
   There needs to be some information stored about source/dest/contacts to be   
   able to do that.   
      
   One other solution could be to re-broadcast these numbers after infection but   
   this would need the infected person to be close again to the original receiver.   
      
   Which seems weird or might not happen ever again.   
      
   One other solution is to start spreading these random infected numbers via a   
   network/routing.   
      
   If this is does anoymous and via broadcasting and no IP then that might work...   
      
   However if there is no source ip can it truely be routed effeciently ?   
      
   Maybe set all destinations on routers and such... it's a bit weird idea.   
      
   Broadcasting would be a useless technology to inform others.   
      
   Even multicast might be of some use.   
      
   Some people might try to indentify these numbers though.   
      
   Bye for now,   
     Skybuck.
